I think you misunderstood. This wasn't a warning that went out to all vendors on the forum - it was just a thread a single individual posted about a weird message they received. You can get access to the vendor forum once you've received a refund of your vendor bond and qualify. I'm confused about what you meant when you said "some vendors [...] still have large amounts of money in accounts and possible orders that have been FE." What do you mean? All you would have to do to prevent this from happening to your account is to ensure that you never provide your password and PIN to a phishing site!
